Description

Technical Field

[0001] The present invention relates to a building structure, and particularly to a high-strength building structure used indoors.

Background Art

[0002] Conventional housing structures are roughly classified into three major types according to the floor height. That is, buildings with three floors or less are low-rise buildings, which are often seen in detached houses and traditional houses. Buildings from the fourth to the tenth floors are mid-rise buildings, which are often older apartment buildings and condominiums. And buildings with ten floors or more are high-rise buildings. When an earthquake occurs, the mid-rise buildings tend to collapse easily. This is because such buildings are often aging and have structural strength defects, or do not meet the seismic standards at the time of construction. In addition, as another factor contributing to the easy collapse, at a height of about four or five floors, the building is highly susceptible to the influence of resonance during an earthquake. As a result, it has to withstand a force equivalent to about four to five times the weight of the building, which is the same as the number of floors. Therefore, it is a weak floor and easily damaged.

[0003] Once a building collapses, the various spaces originally partitioned inside the building are lost due to the collapsed bricks and rubble. Therefore, the residents living in these spaces are extremely likely to be buried alive under the collapsed walls and rubble. Thus, not only is it difficult to carry out rescue activities from the outside, but the buried residents are unable to move under the rubble, and the possibility of survival is significantly reduced. Also, in some situations, even if there is a slightly movable space, it is very dangerous as a whole. Specifically, even if there is a space in the collapsed building where the rescued can take shelter, the structure of the rubble itself is unstable, and secondary collapses and rubble falls may occur due to aftershocks, artificial excavation, or the influence of gravity, etc., and the rescued may be injured or buried again.

[0004] In recent years, rumors have spread in Japan that a super-massive earthquake that no building could withstand will occur. As a result, people are considering ways to increase the survival rate of victims trapped inside collapsed houses and improve the chances of rescue teams finding them, even if buildings do indeed fail to withstand the earthquake. Currently, one proposed concept involves installing containers inside existing houses to create a rescue waiting area amid the rubble. However, containers are extremely large, making it difficult to install them inside existing houses by passing through limited spaces such as doors and windows. Therefore, it was necessary to consider other means that could achieve the aforementioned objectives. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Chinese Patent Application Publication No. 112523547 Specification [Overview of the project]

[0006] The main objective of the present invention is to provide a building structure that can be installed within an existing residential space and can create an evacuation space with sufficient earthquake resistance. As a result, even if the house collapses, the building structure will still maintain its structural shape, forming an evacuation space inside the house after the collapse, allowing residents to safely await rescue.

[0007] To achieve the above objective, the present invention, A precast assembly evacuation reinforcement system installed in an indoor space formed by being enclosed by multiple walls and floors, It includes multiple wall assemblies, multiple fastening cords, and a ceiling assembly. Each of the aforementioned wall assemblies is attached to the aforementioned walls and together encloses the interior space from the sides, and each of the aforementioned wall assemblies includes a plurality of assembly panels that fit together with each other. Each of the assembly plates is fixed to the corresponding wall and is made of ultra-high-performance concrete. The plurality of fastening cords are provided between the plurality of wall assemblies and the plurality of walls, and each fastening cord fastens at least a portion of the plurality of wall assemblies. The aforementioned ceiling assembly is A plurality of horizontal beams are provided above the plurality of wall assemblies in parallel and spaced apart from one another, We propose a precast assembly evacuation reinforcement system characterized by including at least one ceiling body connected to the aforementioned multiple crossbeams and made of ultra-high-performance concrete.

[0008] The advantage of the present invention lies in the fact that it forms an evacuation structure by combining and connecting precast assembly panels indoors, and that the materials for constructing the evacuation space can be transported in sections, passing through existing openings such as doors and windows in the building to be reinforced and installed in the room to be reinforced. This solves the problem of the conventional technology, where it was difficult to transport and install containers indoors. Furthermore, the assembly panels of the present invention are made from ultra-high performance concrete and have extremely high strength, excellent durability, good ductility and toughness, and high crack resistance. Therefore, even if the apartment building collapses, the evacuation structure constructed with the assembly units of the present invention will maintain its structural shape and can withstand the impact of falling debris from the outside, so that people inside can safely maintain the evacuation space until rescue arrives. In addition, the evacuation space structure constructed with the precast assembly evacuation reinforcement system of the present invention can also function as one of the landmarks for rescue teams during their search, greatly improving the possibility of rescuing evacuees inside.

[Modes for carrying out the invention]

[0010] The present invention proposes a precast assembled evacuation reinforcement system provided in an indoor space. Among them, the indoor space is formed by being surrounded by a plurality of walls and a floor, and may include a ceiling that surrounds the indoor space together.

[0011] As shown in FIGS. 1 to 3, the precast assembled evacuation reinforcement system according to the present invention includes a plurality of wall surface assemblies 10, a plurality of ground beam assemblies 20, a plurality of columns 30, a plurality of fastening cords 50, and a ceiling assembly 70. The indoor space of this embodiment is a rectangular parallelepiped space surrounded by four walls, a floor, and a ceiling. Also, some structures are arranged to correspond to the angles of the corners of the indoor space, but it is not limited thereto, and the present invention can also be provided in indoor spaces of other shapes. Therefore, according to the present invention, a high-strength building structure can be assembled in the indoor space. So, even when the building collapses due to an earthquake or other factors, it is possible to prevent the intrusion of rubble and secure a safe space for the victims to evacuate and wait for rescue.

[0012] Each of the plurality of wall surface assemblies 10 is attached to these walls and together surrounds the indoor space from the side. In this embodiment, each wall is taken as a calculation unit as one wall surface assembly 10, so this embodiment includes four wall surface assemblies 10. Also, since the area, size, and door and window arrangement methods of each wall in the actual rooms of a building are not necessarily the same, the area, size, and configuration shape of each wall surface assembly 10 of the present invention can be appropriately changed according to the conditions of the wall to be installed. If necessary, openings (through holes) for installing doors, windows, switches, outlets, fixed furniture, or other equipment can also be provided.

[0013] As shown in Figures 4 and 5, each wall assembly 10 comprises a plurality of assembly plates 11 and a plurality of fixing members 12. The assembly plates 11 are fitted together and arranged to cover the wall surface as much as possible, but are not limited to this arrangement. Each assembly plate 11 is fixed to the corresponding wall via a plurality of fixing members 12. The material of each assembly plate 11 includes ultra-high performance concrete (UHPC), which has excellent compressive strength, tensile strength, and flexural strength, as well as high durability and ductility, allowing it to withstand strong impacts. The detailed properties of the material will not be described in detail. In this embodiment, the material of each assembly plate 11 may further include steel fibers and fire-resistant stainless steel, thereby improving fire resistance and reducing the risk of brittle fracture. Furthermore, in this embodiment, anchor bolts can be used as fixing members 12. The anchor bolts are provided to penetrate each assembly plate 11, are anchored to the wall, and fixed with epoxy resin, but are not limited to this arrangement.

[0014] As shown in Figures 2 to 5, each assembly plate 11 has a first engaging portion 111, a second engaging portion 112, an assembly groove 113, a horizontal groove 114, and a vertical groove 115.

[0015] The first engaging portion 111 and the second engaging portion 112 are located on the left and right sides of the assembly plate 11, respectively. This allows the first engaging portion 111 of one assembly plate 11 to engage with the second engaging portion 112 of the other assembly plate 11, thereby extending the length of the wall assembly 10 in the horizontal direction. In this embodiment, the first engaging portion 111 and the second engaging portion 112 include groove-like structures that are identical in appearance but installed in opposite directions. This allows the first engaging portion 111 and the second engaging portion 112 to engage with each other in a hooking manner, joining two adjacent assembly plates 11 together and preventing separation by lateral forces. In short, the first engaging portion 111 and the second engaging portion 112 of the assembly plate 11 of the present invention form a structure similar to a mortise and tenon, and a mutual locking phenomenon is formed after they are joined together, thus achieving a strong bond for large-area structures. The first engaging portion 111 is recessed on the side of the assembly plate 11 opposite to the wall on which it is provided, and the second engaging portion 112 is recessed on the side of the assembly plate 11 facing the wall on which it is provided. However, the shapes of the first engaging portion 111 and the second engaging portion 112 are not limited to these and may be changed as necessary.

[0016] As shown in Figures 5 to 7, the assembly groove 113 is formed on the upper edge of the assembly plate 11, and in this embodiment, the assembly groove 113 is recessed on the surface of the assembly plate 11 facing the wall on which it is provided. As a result, the lower edge of another assembly plate 11 located above the assembly plate 11 is inserted into the assembly groove 113, which extends the height of the wall assembly 10 in the height direction and prevents the assembly plate 11 from tilting inward, thereby preventing the wall assembly 10 from buckling in the height direction and inward.

[0017] In this embodiment, the multiple assembly plates 11 are fitted together via the first engaging portion 111, the second engaging portion 112, and the assembly groove 113. After this, the surfaces of the fitted assembly plates 11 facing the installed wall are held flat, thereby further improving the adhesion to the wall, but the embodiment is not limited to this.

[0018] Furthermore, the assembly plate 11 of the present invention stretches by fitting together with each other via the first engaging portion 111, the second engaging portion 112, and the assembly groove 113, thus forming a large-area wall surface. When subjected to impact, the load is distributed and the external force is resisted together, preventing deformation. Moreover, since the wall assembly 10 of the present invention is fitted together via the assembly plate 11, it can be assembled after being brought into the interior space through a door or window that connects to the outside. This overcomes the drawback of the conventional container house concept, namely, the problem that the container house cannot be brought directly into the interior space through a door or window.

[0019] As shown in Figures 2, 3, 5, and 6, each assembly plate 11 of the present invention may further be provided with horizontal grooves 114 and vertical grooves 115. The horizontal grooves 114 and vertical grooves 115 are recessed in the surface of the assembly plate 11 facing the corresponding wall on which it is installed, and the horizontal grooves 114 of multiple assembly plates 11 installed at the same height position are in communication with each other. This forms a plurality of horizontal through grooves 13 on the surface of each wall assembly 10 facing the corresponding wall (i.e., each horizontal through groove 13 is formed by the communication of horizontal grooves 114 at the same height position). The horizontal through grooves 13 can be used as wiring routes, for example, for household piping and wiring such as electric wires, communication cables, water pipes, and gas pipes. In this embodiment, fastening cords 50 can be housed in each of the multiple horizontal through grooves 13. Similarly, the vertical grooves 115 of multiple assembly plates 11 located at the same lateral position communicate with each other to form a through groove extending in the height direction, which can provide a route for household piping and wiring, but is not limited to this.

[0020] As shown in Figures 6 and 7, in this embodiment, multiple protrusions 116 are formed on the lower edges of multiple assembly plates 11 located at the bottom of each wall assembly 10, thereby connecting the assembly plates 11 and the underground beam assembly 20, but the embodiment is not limited to this. This part will be described later.

[0021] As shown in Figures 1 and 6-8, each of the multiple underground beam assemblies 20 is provided at the connection points between the floor and the numerous walls, and each is connected to the numerous wall assemblies 10. Specifically, each of the underground beam assemblies 20 in this embodiment corresponds to one wall assemblies 10, and each underground beam assembly 20 has multiple upper connection grooves 201 formed therein, and each of the numerous protrusions 116 is connected to the multiple upper connection grooves 201 of the underground beam assembly 20. Fitting together By being provided, it assists in the positioning of the wall assembly 10.

[0022] In this embodiment, each central beam assembly 20 includes a plurality of underground beam members 21, which are block bodies extending laterally. Each central beam member 21 has a back contact surface 211 that abuts against a wall and a bottom contact surface 212 that is in close contact with the floor. The underground beam member 21 in this embodiment may further have a wiring groove 213 recessed between the back contact surface 211 and the bottom contact surface 212, which facilitates the laying of household piping and wiring. Furthermore, the underground beam member 21 has an upper contact surface 214 facing the wall assembly 10, and the upper joint groove 201 is recessed in the upper contact surface 214. As a result, after the projection 116 of the assembly plate 11 located in the lowest row of the wall assembly 10 is inserted into the upper joint groove 201, the lower edge of the assembly plate 11 comes into contact with the upper contact surface 214 of the underground beam member 21, thereby distributing the load and further stabilizing the position of the wall assembly 10, but the invention is not limited to this.

[0023] Each underground beam member 21 has a connecting groove 215 and a connecting block 216 formed at both opposing ends. In addition, the connecting block 216 of one of two adjacent underground beam members 21 is fitted into the connecting groove 215 of the other underground beam member 21. As a result, multiple underground beam members 21 are connected in series by interlocking tenons, which can accommodate cases where the wall lengths are different. However, the configuration is not limited to this, and the underground beam assembly 20 may have a configuration other than one in which multiple underground beam members 21 are connected in series.

[0024] As shown in Figures 3, 9 to 11, each column 30 is provided between two adjacent wall assemblies 10. In this embodiment, the column 30 is provided in the corner between two adjacent wall assemblies. The column 30 has two joint surfaces 31 that are in close contact with the wall surfaces of the two adjacent walls, and anchor bolts penetrate the joint surfaces 31 of the column 30 from the side into the wall and are auxiliaryly fixed with epoxy resin. In addition, a wiring groove 32 extending in the vertical direction is recessed between the two joint surfaces 31, which is used to install household piping and wiring, but this is not limited to this, and the column 30 does not have to be provided at the connection point of the two walls, nor does it have to have a wiring groove 32.

[0025] Each column 30 has two connecting surfaces 33, and the two connecting surfaces 33 are connected to two adjacent wall assemblies 10. Specifically, in this embodiment, the two connecting surfaces 33 of the column 30 are provided with a structure similar to the first engaging portion 111 of the assembly plate 11. As a result, the column 30 engages with the second engaging portion 112 of the assembly plate 11 of one wall assembly 10 in the lateral direction, and also engages with the first engaging portion 111 of the assembly plate 11 of the other wall assembly 10 via the auxiliary connecting piece 301. This connects the two adjacent wall assemblies 10 tensilely, allowing the load applied to one wall assembly 10 to be distributed to the other wall assembly 10 via the column 30. However, the configuration is not limited to this one, and other configurations may be used.

[0026] In this embodiment, each column 30 further has a plurality of passages 34, which are formed to penetrate the column 30, and each end of each passage 34 forms an opening 341 in two connecting surfaces 33. Specifically, the height position of the opening 341 of each passage 34 formed in the connecting surface 33 is aligned with the horizontal groove 114 of the assembly plate 11, so that the horizontal grooves 13 of the wall assembly 10 located on both sides of the column 30 are in communication with each other via the passages 34 of the column 30.

[0027] As shown in Figure 11, the bottom of the column 30 is connected to two adjacent underground beam assemblies 20 via a corner member 40. Specifically, the corner member 40 has connecting grooves and connecting blocks (not shown) corresponding to two adjacent underground beam members 21, and its shape corresponds to the connecting grooves 215 and connecting blocks 216 of the underground beam members 21, allowing them to be connected to each other. Furthermore, the corner member 40 in this embodiment has a projection 41 that protrudes upward, while the bottom surface of the column 30 has a recess 35, thereby connecting the corner member 40 and the column 30 to each other by a tenon. It should be noted that this configuration is not limited to this one, and the shape of the corner member 40 can be adjusted as needed, and in some cases, a configuration without a corner member 40 may be used.

[0028] As shown in Figures 9 and 10, in this embodiment, each fastening cord 50 is preferably made of prestressed steel strands, is provided between the wall assembly 10 and the wall, and fastens at least a part of the wall assembly 10, but is not limited to this. Specifically, each fastening cord 50 in this embodiment is provided in the horizontal groove 13 of the wall assembly 10 (i.e., a long groove formed by horizontal grooves 114 of assembly plates 11 provided at the same height communicating with each other in series), and in the passage 34 of the column 30. Insertion Furthermore, since the passage 34 of the column 30 communicates with the lateral grooves 13 of the two adjacent wall assemblies 10, the fastening cord 50 extends laterally and surrounds the wall assemblies 10 and the column 30, thereby increasing resistance to impact forces from the lateral direction.

[0029] In this embodiment, the fastening cord 50 applies a lateral force to the column 30, thereby clamping a number of assembly plates 11 in the wall assembly 10 provided between two columns 30. Specifically, this embodiment may have multiple sleeves 60, each sleeve 60 fitted onto the fastening cord 50 and positioned to close one of the openings 341 provided in the passage 34 of the column 30. This allows the fastening cord 50 to transmit tension to the column 30 via the sleeves 60, and further clamp the wall assembly 10 laterally. However, the embodiment is not limited to this configuration, and other configurations may be used.

[0030] Next, as shown in Figures 1 and 2, the ceiling assembly 70 is located above the wall assembly 10, so that the interior space is located between the ceiling assembly 70, the wall assembly 10, and the floor.

[0031] Furthermore, as shown in Figure 12, the ceiling assembly 70 includes a plurality of crossbeams 71, at least one ceiling body 72, and at least one connecting unit 73, the crossbeams 71 can be fixed to the wall or the existing ceiling of the interior space, and the ceiling body 72 is erected on the crossbeams 71. The ceiling body 72 in this invention includes ultra-high performance concrete as its material, thereby being able to resist or receive impacts from falling building debris.

[0032] As shown in Figures 1 and 12 to 15, the crossbeams 71 are located above the wall assembly 10, and the crossbeams 71 are arranged in parallel with spacing between them. Furthermore, each crossbeam 71 has an upward-facing mounting surface 711. In this embodiment, each crossbeam 71 may further have a plurality of upper recessed grooves 712 that are recessed in the mounting surface 711 and arranged at intervals along the longitudinal direction of the crossbeam 71.

[0033] In this embodiment, as shown in Figures 1, 14, and 15, the crossbeam 71 includes a plurality of edge beams 71A provided on two opposing walls and extending along the wall surfaces of the corresponding walls, and at least one intermediate beam 71B installed alongside the edge beams 71A at a distance. The edge beams 71A have an installation surface 711 on only one side, and a ceiling body 72 can be erected on only one side, whereas the intermediate beam 71B has installation surfaces 711 on both sides, so a ceiling body 72 can be erected on both sides. The intermediate beam 71B may be fixed to the existing ceiling of the interior space, or both ends may be extended to the wall and fixed to the wall. In this embodiment, the edge beams 71A are open-type steel beams made of C-shaped steel, and the intermediate beams 71B are open-type steel beams made of I-shaped steel. Furthermore, both the edge beam 71A and the intermediate beam 71B have an intermediate section 713, a top plate section 714 facing the intermediate section 713, and a bottom plate section 715. The intermediate section 713 extends vertically, and multiple through holes 7131 are formed horizontally. The top plate section 714 and the bottom plate section 715 are connected to the upper and lower ends of the intermediate section 713, respectively, and extend horizontally, but are not limited to this. In this embodiment, the installation surface 711 is located on the bottom plate section 715 of the edge beam 71A and the intermediate beam 71B. In addition, multiple fixing holes 7132 and 7141 are formed through the top plate section 714 and the intermediate section 713, thereby allowing anchor bolts to be inserted into these fixing holes 7132 and 7141. Insertion These horizontal beams 71 are then fixed to the existing ceiling or wall of the interior space, but are not limited to this. Furthermore, a wiring groove 718A is recessed in the wall-facing surface of the edge beam 71A in this embodiment, and household wiring and piping can be laid in the wiring groove 718A, but are not limited to this.

[0034] Next, as shown in Figures 1, 12, 17, and 18, the ceiling body 72 is connected to a plurality of crossbeams 71. Specifically, this embodiment includes a plurality of ceiling bodies 72, each of which is an arc-shaped plate and has a concave surface 721, and is installed between a number of crossbeams 71 that are spaced apart and arranged side by side, with the concave surface 721 facing the floor. Therefore, when installing the ceiling body 72, the user can adjust it according to the actual size of the room space. For example, if the room space is small, the intermediate beams 71B are not installed, only the edge beams 71A are installed, and the ceiling body 72 is installed between the two edge beams 71A. On the other hand, if the room space is large, when an additional row or more rows of intermediate beams 71B are installed, the ceiling body 72 can also be installed between one edge beam 71A and one intermediate beam 71B, or between two intermediate beams 71B.

[0035] Furthermore, the ceiling body 72 of this embodiment has a plurality of mounting edges 722 that contact the mounting surfaces 711 of the plurality of crossbeams 71, each mounting edge 722 is wavy and extends along the longitudinal direction of the connected crossbeams 71, and has a plurality of lower protrusions 7221, each of which is housed in a plurality of upper grooves 712 formed on the mounting surface 711 of the contacting crossbeam 71, and the ceiling body 72 is engaged with the crossbeams 71 so that it does not slide relative to them. Note that this embodiment uses the above configuration, but is not limited thereto.

[0036] In this embodiment, each ceiling unit 72 may have at least one connecting portion 723 fixed to the side of the ceiling unit 72 opposite to the floor, and formed such that a connecting hole 7231 penetrates it from the side. The connecting portion 723 is preferably formed by integral molding, and the connecting portion 723 has a substantially annular structure as the direction in which the connecting hole 7231 penetrates faces the crossbeam 71. In this embodiment, the above configuration is used, but the embodiment is not limited thereto.

[0037] In this embodiment, when installing the ceiling body 72, fitting numerous short ceiling bodies 72 in the extending direction of each horizontal beam 71 prevents the volume of the ceiling body 72 from becoming excessive, which would prevent it from being brought into the interior space through openings such as doors and windows. As shown in Figure 18, in this embodiment, when molding and manufacturing the ceiling body 72, semi-annular structures 7232 can be molded at both ends where they are to be joined with other ceiling bodies 72. This allows the two ceiling bodies 72 to be joined together, and then the semi-annular structures 7232 can be combined to form a connecting section 723. This configuration not only simplifies the manufacturing of the ceiling body 72 but also improves the convenience of transporting the ceiling body 72, thereby reducing the risk of defects occurring in the connecting section 723.

[0038] As shown in Figures 1, 12, and 16, the connecting unit 73 is provided on the connecting portion 723 and connected to the edge beam 71A, or connected to the connecting portions 723 of the two ceiling bodies 72 located on opposite sides of the intermediate beam 71B, and also through the through hole 7131 of the intermediate beam 71B. Insertion The connecting unit 73 not only transmits the load applied to the ceiling body 72, but also directs it toward the installation surface 711 of the crossbeam 71 via the arc shape of the ceiling body 72. mosquito By applying downward pressure to the ceiling body 72, the lower projection 7221 of the installation edge 722 of the ceiling body 72 is securely accommodated in the upper groove 712 of the installation surface 711 of the crossbeam 71, thereby stabilizing the position of the ceiling body 72 and preventing displacement.

[0039] Specifically, the connecting unit 73 of this embodiment comprises a rod member 731 and at least one fastening member 732. Below, the connection method between the horizontal beam 71 and the ceiling body 72, and the connection method between two ceiling bodies 72 will be described separately.

[0040] Figure 16 shows a method of connecting the crossbeam 71 and the ceiling body 72 using a connecting unit 73. In this method, one end of the rod member 731 is connected to the connecting hole 7231 of the connecting part 723. InsertionThe other end is fixed to the edge beam 71A of the crossbeam 71. In this embodiment, a high-tensile steel rod having an external thread structure is used as the rod member 731, and an embedded steel member 716A is embedded in the wall-facing surface of the edge beam 71A. A welding nut 717A is welded to the embedded steel member 716A to connect and lock it with the rod member 731, but the connection method is not limited to this.

[0041] The fastening member 732 is movably provided on the rod member 731, and at the connecting portion 723, Opposite side of crossbeam 71 It is pressed against the rod member 71. In this embodiment, the fastening member 732 includes a bush 7321 and a wing nut 7322, which the worker rotates manually to press and restrict the position of the bush 7321 on the rod member 731. By tightening the wing nut 7322 to fix the bush 7321 to the connecting part 723, the tension of the rod member 731 is transmitted to the connecting part 723 via the fastening member 732, so that the ceiling body 72 is pulled in the direction facing the wall. The ceiling body 72 is an arc-shaped plate and its concave surface 721 faces the floor, so that its tensile force is transmitted along the arc-shaped plate to the installation edge 722, so that the installation edge 722 is pressed against the installation surface 711 of the crossbeam 71, so that the lower recess and the upper recessed groove 712 engage stably, and the ceiling body 72 is fixed so that it does not slide against the crossbeam 71. The fastening member 732 can also be used at the point where the inner weld nut and the rod member 731 are connected.

[0042] Next, refer to Figure 12. Figure 12 shows a method in which a connecting unit 73 connects two ceiling bodies 72 to each other. In this connecting method, the connecting unit 73 is located on both sides of the intermediate beam 71B, thereby connecting two ceiling bodies 72 connected to the same intermediate beam 71B. In this embodiment, the connecting unit 73 has one rod member 731 and two fastening members 732. Similarly, a high-tensile steel rod with an external thread structure can be used as the rod member 731 in this connecting method, and the rod member 731 is inserted into the through hole 7131 of the intermediate beam 71B. Insertion It will be done 。As a result, both ends of the rod member 731 are connected to the connecting holes 7231 of the connecting portion 723 of the two ceiling bodies 72. Insertion It will be done.

[0043] The fastening members 732 are movably provided at both ends of the rod member, and the connecting portion 723 of the two ceiling bodies 72 is located between the two fastening members 732, so that the two fastening members 732 are pressed against the connecting portion 723 of the two ceiling bodies 72 in opposing directions. Similarly, the fastening members 732 include a bush 7321 and a wing nut 7322, and the tension of the rod member 731 is transmitted to the two ceiling bodies 72 by the two fastening members 732 being pressed against the connecting portion 723 of the two ceiling bodies 72 in opposing directions, so that the mounting edges 722 of the two ceiling bodies 72 can be brought into close contact with the mounting surfaces 711 on both sides of the intermediate beam 71B.

[0044] According to the above configuration, even if a building equipped with the present invention is damaged or collapses due to an earthquake or other disaster, the ceiling assembly 70 and wall assembly 10 are installed covering the walls and ceiling surrounding the interior space equipped with the present invention, thus ensuring a safe evacuation space even when subjected to external forces. As a result, victims can take refuge in the space enclosed by the present invention and wait for rescue while ensuring their safety. Furthermore, the wall assembly 10 of the present invention includes an assembly plate 11 precast from high-strength, ultra-high-performance concrete and is surrounded by fastening cords 50 made of prestressed steel strands. In addition, the assembly plates 11 are further fitted together via a first engaging portion 111, a second engaging portion 112, and an upper recessed groove 712 to achieve a mutual locking effect, thereby dispersing the impact force received and preventing the collapse of the assembly plate 11. In addition, the columns 30 and underground beam members can further reduce the possibility of collapse by dispersing the lateral impact force applied to one side in accordance with the combination of connections of each wall assembly 10. Therefore, the present invention can effectively resist lateral impact forces, thus preventing collapse and maintaining the interior space.

[0045] On the other hand, the ceiling body 72 of the ceiling assembly 70 also contains ultra-high-performance concrete, so it is resistant to impact, and in particular, it can catch falling rubble and debris, protecting users in the room from being hit. Furthermore, since the ceiling body 72 is an arc-shaped plate and its concave surface 721 faces downward, it can not only effectively distribute the load but also guide the caught debris to the location of the crossbeam 71, thereby creating a safe area below the ceiling body 72. Moreover, even if the ceiling body 72 were to fall, because it is an arc-shaped plate and its concave surface 721 faces downward, it can provide a space for users to take cover and seek protection.

[0046] Even if a building unfortunately collapses, the structure of the present invention is robust and will not easily collapse even when subjected to impact, thus preserving the interior space and allowing it to be used as an evacuation space. This makes it easier for rescue workers to find the structure among the rubble and debris of the collapsed building, and as a result, rescue workers can quickly rescue victims.

[0047] As described above, the present invention allows for the construction of a high-strength protective shelter within the interior space of an existing building by assembling and installing it according to the existing walls, floors, and spatial arrangement. This ensures the safety of those trapped inside while awaiting rescue, as it can withstand external impacts while maintaining the structural shape and interior space. Compared to the "container installed inside the room" structure proposed in the prior art, the present invention not only has higher strength than a steel container house, but also modularizes and divides each structure, and by pre-casting small-volume modules, it can be brought into the room through existing openings such as doors and windows and installed. Furthermore, because it is a modular structure, workers can complete the assembly quickly and easily. Therefore, the present invention has many advantages compared to the prior art and can also be applied to reinforcing the interior structure of aging mid-rise buildings, thus enabling responses to disasters that may occur in the future.
